How Brick Quality Affects Masonry Performance
Description
Brick quality affects how masonry holds up, looks, and performs over time. Durability, strength, and appearance are all used to judge which bricks fit a specific job. These features help builders choose bricks for walls, facades, and other construction uses.
Durability is closely tied to freeze-t...

冻融是指砖中吸收的水在冻结时膨胀,在解冻时收缩,从而导致砖降解的过程。砖抵抗此类伤害的能力称为耐久度。
砖的耐久性是分级的,SW 级砖因其高强度和低吸水率而最耐用,其次是 MW 级砖,然后是 NW 级砖。
建筑砖和面砖的抗压强度通常在每平方英寸 1500 到 3000 磅之间。
砖砌体的强度主要取决于砂浆、钢筋和砖本身的强度。
砖的外观受其尺寸变化、形状变化以及砖面或边角可见损坏程度的影响,碎屑的数量也是砖外观的一个考虑因素。
砖的颜色主要来自粘土类型,而它们的表面纹理和外观是由制造过程中使用的模具、模具或附件塑造的。
